MdeModulePkg/Xhci: Remove TDs from transfer ring when timeout happens
The error handling for timeout case is enhanced to remove TDs from
transfer ring. The original code only removed s/w URB, but the h/w
transfer descriptor TDs didn't get removed. It would cause data lost
for data stream peripheral, such as usb-to-serial device, from the
s/w perspective.
